The relevance of residual stresses in engineering components is being increasingly appreciated by modern engineers concerned with design and performance. The non-destructive evaluation of such stresses has provided a challenge which has been addressed by the use of X-ray diffraction to characterize near-surface stresses. The extension of diffraction stress measurements to include neutron diffraction represents a major advance. Use of the penetrating power of neutrons is ideally suited to the determination of macrostress variation through thick components and of microstresses in composites and multiphase alloys. <br/> This collection of papers on the subject is the first of its kind and represents a definitive summary of the field. With contributions by most of the world's experts, it gives a comprehensive treatment of the theory, practice and problems in the measurement of residual stresses using neutrons, with references to virtually all work currently in print. It provides state-of-the-art information about the uses and limitations of the method, with numerous examples. It is appropriate both for those currently using X-ray methods, and for engineers and scientists considering the use of neutrons for industrial or research problems involving residual stress characterization in metallic, ceramic or composite systems. <br/>
